I do and have for the past 10 years. Watch your elbows if that's you in the vid. Avoid lockout.
As a general rule, reps in the 2-6 range develop strength, those in the 8-12 range develop size and anything above 12-15 works shape, cuts and detail. Everyones body is a bit different and will react a little differently to different rep schemes, but I've personally never been able to gain size from reps under 6. Strength and size are not the same, but it helps to boost strength first before trying to add size.
And diet is close to 75% of the equation. Lift all you want, but if your diet isn't up to par, gains won't be either.
